in 1999, I had a 7 STW built with a 1-11T, Pac Nor super match 3 groove. Used a zero freebore 7 STW reamer. 140g Nosler combined Tec bullet at 3750 shoots tiny groups, took 12 rounds to work up a load with IMR 7828 and 215's.
Twist the barrel according to the bullets you want to shoot, success will be easy to achieve.
